I do a lot of volunteer work and find these useful for any number of applications not just for holding papers. For example - combined with pushpins I used the clips to run an extension cord along a wall & up off the floor where students might trip over it.
I ofter have a need to secure papers so the do not blow out of my tractor. I am an OTR Over the road truck driver. This clip it light weight easy to use and extremely strong. The only drawback it that they come in a little tub you cannot buy just two.
